Dimmer switch



FIG. 1 is a perspective view of a dimmer switch according to our new design.

FIG. 2 is a front elevation view thereof.

FIG. 3 is a left side elevation view thereof.

FIG. 4 is a right side elevation view thereof.

FIG. 5 is a top plan view thereof; and,

FIG. 6 is a bottom plan view thereof.

The rear view forms no part of the design and is omitted. The portions of the drawings appearing in broken line show unclaimed subject matter only and do not form a part of the claimed design. 

We claim the ornamental design for a dimmer switch, as shown and described.
